Whoever Said It Was Among The Last Seven Nights
Sunan Abi Dawud
حَدَّثَنَا الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " تَحَرَّوْا لَيْلَةَ الْقَدْرِ فِي السَّبْعِ الأَوَاخِرِ " .
Narrated Ibn 'Umar: The Messenger of Allah (ﷺ) as saying: Seek lailat al-qadr in the last seven days.
